Cover: The cover depicts the novel synthetic scheme for the stereoblock poly(lactic acid) (sb‐PLA) by solid‐state polycondensation of a stereocomplexed mixture of poly( L ‐lactic acid) (PLLA), and poly( D ‐lactic acid) (PDLA), having medium molecular weight. First, melt‐polycondensation of L ‐ and D ‐lactic acids is conducted to obtain the PLLA and PDLA, respectively. In the second step, these polymers are melt‐blended to form the stereocomplex. Then, the solid‐state polycondensation of the melt‐blend affords the sb‐PLA with high molecular weight and high melting temperature without formation of single polymer crystals of PLLA or PDLA. Further details can be found in the Full Paper by K. Fukushima, Y. Furuhashi, K. Sogo, S. Miura, and Y. Kimura * on page 21.
